This invention relates to new and useful improvements in valves for engines and motors. Y Y The object of the invention is to provide] avalve which may be for air, oiland steam in combination or separately 1n proper pro rtions and without the use of the other flui s and under high pressure and high temperatures, as the case may mrebuilt with standard frame sizes, shafts etc, and by. use of said valve converted from a combined'steam, air and oil engine to a con- (lensing or non-condensing steam." eng ne, or

to an oil engine under the two cycle prin'-.'

'ciple, single or double acting and which may be built either horizontal or vertical.

An in! ortant object of the invention is provi e a'common valve for porformm fluid underv pressure .for' blowing out the scavenging gases or products 'of combustion through. the exhaust. opening;

Y A further object/is to V-frovide a valvety slidable in the cylmd'erand has a sump I engine cylinder whereby a better process 0 atomizing and semen iggcan-beobtained with'a more simple an cient-means for performingthese functions than has'been' heretofore evolved. ,Anoth'erobjectlis to provlde' a. valve in the form of an attachmentwhich ma be connected inthe head of an engine wit out material alteration of the latter.

-. A'construction designed to carry out the invention will be hereinafter described together with other features of the invention.

, The invention will be more readily under- Fig. 1 is .a fragmentary elevatlon of an nipped with a valve. constructed in accor ance withmy invention, a portion being illustrated in sectlon, Fig.2 is a vertical sectlonal view, Fig. 3 is a crosssectional view on-th 3-3 0f Fig. 2,

Rig. 4 is a detail of the atomizlng head I and nozzle; and

" a Fig.- 5 is an underside view of the same. In the drawings the numeral 10 designates a cylinder of an engine having exhaust ports 11' of the cage pe. A piston head 12 is in its compression end. An annular head 14 is secured on the cylinder by means of bolts 15 and has a concentric water space 16. Such parts arev found in manyengmes and are secondary to my invention.

a The head has an inwardly tapered central bore 17 considerably less in diameter than thebore (lithe-cylinder. A tapered valve case 18 is tightly fitte d into the'bore 17 and 'Aparticular ob ect is to PI'OVI eavalve which-will enable anengine or motor to be At the inner end of the tube I provide a chamber 22 into which is screwed a diskhead23 having its under surface convex. A

plurality of nozzles 24am radially mounted in the convex surface of the head so as to 5 read the discharge radially of the cyliner. These nozzles may vary in construction and arrangement and are shown 'in detail in Fig. 4. At the top of the chamber 22 I provide a valve seat-25 adapted to recelve an upwardly seating valve head 26 carried by a valve stem 27.

The valve'stem extends through a dull- ,ing box 28 at the upper end of' the tube and receives a cap- 29; 'upper end of the tube a'coiled expansion tween the cap and the spring 30 is confined about the stem. This spring normally holds the head 26 seated. Just under the stufiing box a pipe 31 enters the tube from one side, while a second pi 32 enters the tube from the opposite si e.- Air or steamer both may be supplied through the pipe 32. It Is to be understood that the steam or air may be omitted and stood from a reading of the following specification and by reference to the accompan ing drawings, in which an example of t o invention is shown, and wherein:

the fuel oil alone utilized. The .valve steam -within the tube has: a special thread 27',

which causes the fluids, passing down the tube to take a spiral course and whereby the molecules are more thoroughly broken up and a more complete mixture of-the conejected through the nozzle 23- will be {any atomized and highly combustible,

. The tube within the valve case is Bill rounded by avertical. annular chamber 33.

-In the lower end of the-chamber33, (Fig. 2)

spring 40 is confined under a yoke, .41.

'vstituent elements, is obtained. The charge I neachstema- In the lower portion of the cavity 33 (Fig. 1) are ball valves 43 which are supported on apertured lower seats 44. These all valves may be omitted and the work done entirely by the valves 37,.which latter is preferable.

Fluid supply pipes 45 enter the top of the chamber 33. Suitable means are provided for operating the valve 26 and the yoke i1 which operates the valve 37 In 0 eration the full charge is supplied throng pipe 32 and air or steam or bot are supplied through the pipe 31. This mixed fue fluid'passes down the tube, being given g zspiral or whirling motion by the thread and atomization is promoted. The valves 37 will open when the piston head 12 uncovers the exhaust ports 11 at the bottom of its stroke and the fluid which has been stored inthe chamber 33, under pressure, will pass into the cylinder and blow out the scavenging gases through said exhaust ports.

The pipes 45 are provided with pressure regulated valves 46 of a suitable type arranged to open under a predetermined pressure.- The valves 37 remain open and permitthe pipes 45 to supply fresh air at atmospheric pressure, or air from a store e tank to the-cylinder 10, which is thus fille above the piston. During the up stroke of the piston the valves37 remain open, whereby the chamber 33 is filled with compressed air-for scavenging and compression is built up at the top of the cylinder. These valves are timed to close 'ust rior to the o enin of 3 p p g i ng a central tube, an atomizing head at the the valve 26 which admits the fuel charge through the nozzles 24. This traps the compressed air in the chamber 33. If the valves 43 are used they will close against their seats 44 immediately following the ignition of the charge and reduction of the pressure of the air in the cylinder. I

It is also the purpose of the valves 37 to function for starting the engine. Compressed air for this purpose is supplied through the pipes 45. A reversing mechanism (not shown) for reversing the time of opening of said valves for scavenging, wil be emplo d, and thus the valves 37 will open at t e upper end of the stroke of the piston for admitting the starting pressure,

Where the en ine is to be operated entirely on steam t e valve 26 may be fastened and steam admitted through the pipes 45 or otherwise su plied to the chamber 33. The

valves 37 wil then be timed to open at the upper end of the stroke of the piston. Other fuel adjustments are easily possible. The Y a self contained unit and the head 14, could be valve case 18 bein readil fitted wit altere cylinder, head or other part. But by manipulatin the parts of the valve, as described, the engine may be converted from oil to steam or air or any other ccualnnatlon whereby the molecules are broken up I if necessary without changing the of a valveldevice operative on 'the suction stroke of the piston for admitting a fuel charge to the cylinder, said valve device he ing provided with" afluid stora e chamber and means governing the flow o fluid back and forth between said storage chamber and the cylinder, said means coacting with the piston, in the movements of the latter, for establishing communication between the stora e chamber and cylinder and supplying uid independent of the fuel char e to the cylinderv on the suction stroke 0? the piston, for maintaining communication between the storage chamber and cylinder during a portion of the'eompression stroke of the piston for storing up such fiuid under piston pressure in said'chamber and then closing communication betweenthe chamber and cylinder, and for releasing said pressure on the working stroke of the piston and when the exhaust port is open to blow out the gases'remaining in the cylinder.
